Revit Ceilings and Roofs
Revit Ceilings and Roofs
33 In the project browser, double-click Ceiling Plans > Level 1.
- 34 Add ceilings to the rooms:
-On the Modeling design bar, click Ceiling.
-On the options bar set ceiling type: Compound Ceiling: 600 x 600 mm grid.
-Click once inside each room to automatically generate the ceilings.
Although added with just a single click, ceilings, like floors, are also sketch based. The Autogenerate tool is helpful, but if you need to change the shape, you must select the ceiling and click Edit on the options bar.
Selection Tip Hold your cursor over the object, and press TAB:
- Sometimes selecting objects that are colinear with other objects can be difficult.
- Hold your cursor over the edge of a ceiling (which is also the same location as a wall).
- Press TAB a couple times to cycle through the objects that are at the cursor location.
Anything that you select with a left mouse-click is available as a tooltip and at the lower-left corner of the window at the status bar.
Add a Roof
You can create roofs by footprint or by extrusion. This exercise walks you through creating a roof by footprint. A later unit illustrates roof by extrusion.
35 In the project browser, open Floor Plans > Level 2.
36 On the Modeling design bar, click Roof > By Footprint. You are in Sketch mode. The default Sketch mode is Pick Walls.
If the Pick Walls option is selected, the roof boundary follows the wall’s position, and any further changes to the wall location are automatically propagated on the roof shape.
Pick Walls is equivalent to assigning a constraint to maintain design intent or structural sense.
37 On the options bar in the Overhang box, type 500, and make sure that Defines Slope is selected.
When clicking, make sure your cursor is positioned on the exterior side of the wall or the overhang will be on the wrong side.
38 Highlight any exterior wall. Press TAB to highlight all four. Click to create the roof footprint.
Using TAB to select is a convenient way to select chains of components with a one-click operation. It is widely used in Sketch mode.
39 On the design bar, click Finish Roof.
40 A dialog box asks if you want to attach the highlighted walls to the roof. Click Yes. By clicking Yes, you are attaching the walls to the roof and thus defining an explicit relationship: if the roof changes height, the attached walls follow accordingly.
The view cuts the roof because the view range the second plan is set to show a floor and the cut plane is set at 1200 mm. You change this in the next exercise.
The 3D view category is automatically created once a 3D view is opened. You can customize view grouping so the project browser can display the view groups in many different ways.
41 Open the 3D view by clicking the 3D icon to see the roof.
You eliminate the slope from the east and west sketch lines to create gable ends on these sides.
You change the slope of the north and south lines to a lower pitch.
Make Gable Ends and Adjust Roof Slope
In this section you reenter Sketch mode to modify the slope of the sketch lines.
42 Go back to Floor Plan Level 2.
43 Select the roof.
On the options bar, click Edit.
44 Select the left and right roof footprint lines.
On the options bar, clear the Defines Slope check box.
Clearing the Defines Slope check box tells Revit Architecture that this edge of the roof does not slope and is therefore a gable end to the roof. To select more than a single item, hold down CTRL as you select the objects.
Revit Architecture manages the slopes by automatically adjusting most geometrical data. If the eaves are not correct, use the Align Eaves tool to correct the problem.
Hold down SHIFT to remove objects from an existing selection set.
45 Select the top magenta line. Text displaying an angle value appears.
Sketch lines are displayed in magenta, which you can change to any other color: Settings > Line Styles > Lines(Sketch).
46 Click the blue text. Change the value to 12.
Repeat for the bottom roof sketch line.
Sketch lines are displayed in magenta, which you can change to any other color:
Settings > Line Styles > Lines(Sketch).
Change the value of the roof slope by selecting the slope-defining line and opening its Properties dialog box, where you find the angle parameter.
47 On the Sketch design bar, click Finish Roof.
While lower in height, the roof is still cut by the view range of level 2.
